Sites

Abstract:

This layer contains point locations for operating Permitted
Industrial and Hazardous Waste Locations in Texas. Facilities which
store, process, or dispose of hazardous waste (except where such
storage and/or processing is excluded from permit requirements in
accordance with 30 Texas Administrative Code (TAC) Section 335)
must obtain a permit pursuant to the Texas Solid Waste Disposal
Act. The Industrial and Hazardous Waste Permits Section of the TCEQ
maintain a database of these facilities, which is represented
geographically here.

Level 3 Certification - This layer does not meet the minimum 25
meter agency standard. The layer was certified with known problems
that have been documented in the metadata. It is not suitable for
high-precision measurement applications.

Horizontal_Positional_Accuracy_Report: The facilities report
location information to the TCEQ, however, it is not known by which
method these coordinates are obtained. The GIS Team did a simple
evaluation of the site locations using TIGER county boundaries as a
reference. Of 224 sites, 19 fell in wrong counties. These will be
corrected by IHW staff, however they are included in the current
coverage.

Source_Contribution: All data in this spatial dataset was
extracted from the TCEQ Hazardous Waste Registration Database.

Process_Step:

Process_Description: Arc/Info software is used to create a
point coverage from ascii data extracted from the Hazardous Waste
Registration Database. Coverage is then projected to the TCEQ
standard map projection (TSMS).

corresponds to the Texas State-wide Mapping System (TSMS) defined
in the Texas GIS Planning Council's GIS Data Standards. TSMS uses
measurement units of meters.

Geographic ID Number. This number, assigned during the TCEQ GIS
Certification and Update procedures, uniquely identifies each
facility, monitoring station and incident site tracked by TCEQ.
This number is permanent and non-reusable. GIN numbers 7000001
through 7999999 are reserved for Permitted IHW sites.

Overview Description:

Entity_and_Attribute_Overview:

The .pat table contains a TCEQ Geographic Identification Number
(GIN) and a TCEQ Hazardous Waste Registration Number (FID). The
.dat tables also contains these two attributes (GIN should be used
as a relate key), along with other attributes taken from the TCEQ
Hazardous Waste Registration database. Those attributes noted with
an asterisk (*), are not considered very reliable.
